SHUTTLE FOR EMBROIDERY-MACHINES.

Specification of Letters Patent.

Patented Sept. 26, 19H6.

Application led January 27, 1914. Serial No. 814,686.

To all whom t may concern.'

Be it known that I, MORRIS SorronNrnLn, a citizen of the United States, and resident of Rorschach, Canton of St. Gall, Switzerland, have invented new and useful Improvements in Shuttles for Embroidery-Machines, of which the` following is a full, clear, and exact specication.

The necessity, in shuttles for embroidery machines which arises from Vwell known causes, to provide as large a thread spool as possible, has recently caused the longitudinal shuttle hitherto in use to be replaced by a shuttle constructed wider in diameter or by a shuttle suitably prolonged to the rear. But this widening or lengthening of the body of the shuttle is obviously restricted within certain limits by the shape of the shuttle track and the arrangement of the shuttle drivers.

The present invention pursues the same object of enabling the use `of larger spools, but attains it by other means and without abandoning the usual arrangement and length of the shuttle.

The shuttle according to the present invention is distinguished by the arrangement that while one or both longitudinal sides of the shuttle body have a lateral enlargement or widening, the spool entrance opening of the shuttle is extended between the ends of the shuttle in the one or both flanks up to the lateral widening thereof by means of an aperture which allows of a spool to be introduced through said spool entrance opening, the thickness of which is greater in the middle than the width of the spool entrance opening of the shuttle. This construction of the shuttle enables moreover the unaltered retention of the ordinary guiding parts of the shuttle track while nevertheless a large spool can be inserted into the shuttle body.

It is advisable to arrange the cover serving for the closure of the spool entrance opening of the shuttle in such a manner that it partly or completely engages in or closely fits into the said side aperture of the shuttle body. Moreover, the said cover is advantageously provided at its outer side with a running rib, which is so arranged that it completes the corresponding shuttle ank guide at` the place of the said side aperture.

The accompanying drawing illustrates two constructions of the invention.

Figure l shows a view from beneath of the preferred form (viewed from the side of the cover). Fig. 2 shows a side elevation. Fig. 3 shows an end view (viewed from the point of the shuttle). Fig. 4 shows a transverse section of the shuttle body illustrated in Fig. l. Fig. 5 shows a transverse vsection through the shuttle body of a second form.

The shuttle constructed according to Figs. 1 to 4: possesses on the side turned toward the shuttle track a the necessary spool entrance opening for the insertion of the spool in the interior of the shuttle, provided with the cover b, which is pivoted to the rear end of the shuttle body at c in the usual manner and is provided with a thread exit hole d and a thread tension spring c. The shuttle is guided rectilinear by means ofits two side flanks upon the shuttle track a between the stitch plate f and the usual outer guide rail g of the track a (Fig. In the side flank c' turned away from the plane of the fabric, the body of the shuttle is widened out over the sole of the shuttle so as to overhang the guide rail g, and is provided in the longitudinal direction between the ends of the shuttle with an underneath aperture m, which extends from the spool entrance .opening up to this widening or overhanging portion, so that through the shuttle entrance opening in consequence of the aperture m, a spool can be inserted which is of a larger diameter in its middle part than the lwidth of the spool entrance opening.

As may be seen best from Figs. 2 and 4. the shuttle cover Z2 is so formed that it fits to the curvature of the shuttle body, and thereby closely engages in the side aperture m, so that there is no projecting edge at the shuttle body, which might occasion a sticking of the thread loop. from the drawing, the shuttle cover or covering lid b is so arranged that it engages with its body or main part between the inner walls of the side flanks of the shuttle a small distance above the guiding edges thereof, while a lateral projecting Ipart of the cover b is curved around upward to closely engage within the longitudinal aperture m provided for in one of the side flanks, both the side flanks thus extending below the cover (Fig. 4) to form the guiding sole for the shuttle body, so that the As will be seen cover in its main part is out of contact with the guide-way of the shuttle track a.

Owing to the aperture m, the iiank guidance of the shuttle upon the side turned away from the plane of the fabric is lim- .ited to the flanking pieces n, al (F ig. 2).

However the shuttle cover I) is provided at its outer side with a running rib 0 arranged longitudinally, which rib is alined with the flank pieces n, nl, so that it completes at the point of the aperture m, the flank guidance. But it is obvious, that the said running rib o on the cover may easily be dispensed with, when it is desired, as shown in the modification of Fig. 5.

That I claim is:

1. A shuttle for embroidery machines, having two side ilanks, each provided with a guiding edge or sole, a widened overhanging portion in at least one of said side flanks, a spool entrance opening between the guiding edges of the side iianks, a longitudinal aperture in at least one of the side iianks extending upward from its vguiding edge, and a closing cover for said opening' having its body arranged between the side flanks and a laterally projecting part eX- Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents.
